agent's token refresh failed mid-run, scan aborted

Not specified by the original author.

TL;DR

App auth tokens expire on their own schedule, and an agent that logs in once will fail every request after expiry. Refresh the token proactively before it dies, keep a lifetime buffer (refresh at 80 percent of token life), and on expiry signals pause, refresh, verify with one probe, and resume from the checkpoint. Treat token handling as engagement infrastructure, not scan logic.

auth token expired mid-engagement: agent authenticated scan of authorized app failed

Use this when

• An authenticated app scan fails partway with expired-token or invalid-token errors.
• The app issues tokens with a known lifetime shorter than the scan duration.
• The agent currently logs in once and never refreshes.

Not for this skill when

• Login never worked. That is a credential or flow problem, not an expiry problem.
• The scan tool itself crashed. Check for the token-expiry error text first.
• The token belongs to an app outside your authorized engagement. Do not use it.

Steps

1. Learn the token lifetime from the login response or the engagement docs. Verify: you can state the lifetime in minutes.
2. Schedule proactive refresh at 80 percent of the lifetime, in the background, without pausing the scan. Verify: a refresh event is logged before any expiry error appears.
3. Teach the agent the expiry signal: token-expired error bodies or sudden 401s on previously working requests. Verify: the agent names token expiry as the cause instead of blaming the target.
4. On the signal, pause new requests, run the refresh flow, and verify with a single authenticated probe. Verify: the probe succeeds before the scan resumes.
5. Resume from the checkpoint. Verify: no target is scanned twice and none is skipped.

Variant phrasings

bearer token expires during long scan

Common phrasing.

agent refresh auth token mid engagement

Agent-workflow phrasing.

authenticated scan 401 halfway through

Symptom-level search.

Compatibility: token-based app auth generally. The 80-percent refresh rule works for any stated lifetime.

Why it happens

Tokens are issued with lifetimes tuned for human sessions, not multi-hour agent scans. The agent's plan has exactly one login step, so expiry lands as a surprise mid-run, and the error text looks like the app rejecting the scan rather than the clock running out.

Edge cases / pitfalls

• Refresh tokens expire too. Track both lifetimes; a dead refresh token needs the full login flow again.
• Clock skew between the agent host and the app server can make a "valid" token read as expired. Sync the clock before debugging the flow.
• Never log token values. Log the refresh event, the expiry timestamp, and the outcome, nothing else.

Thread query: auth token expired mid-engagement: agent authenticated scan of authorized app failed

TL;DR: App auth tokens expire on their own schedule, and an agent that logs in once will fail every request after expiry. Refresh the token proactively before it dies, keep a lifetime buffer (refresh at 80 percent of token life), and on expiry signals pause, refresh, verify with one probe, and resume from the checkpoint.

TL;DR

Continuing to scan after auth fails produces unauthenticated, incomplete results that look complete. Fail closed: on auth errors, stop the run, mark results partial, and alert.

Error

agent's vault token expired mid-run and it kept scanning unauthenticated: auth error

Steps

1. Confirm the silent continuation: logs show auth failures followed by more scanning. Expected: the fail-open proven.
2. Add an auth check before each phase; on failure, halt. Expected: fail-closed behavior.
3. Mark any results gathered after the auth failure as partial and untrusted. Expected: honest reporting.
4. Alert on auth failures immediately; they may indicate revocation, not just expiry. Expected: fast response.
5. Re-run the affected phases with valid auth. Expected: trustworthy results.

When to use

• Agents continuing after auth failures.
• Building fail-closed automation.

When not to use

• Permission errors with valid auth (different handling).
• Intentional unauthenticated phases (then mark them as such).

Tool compatibility

• Vault auth; agent run control.

Variant phrasings

agent scanned without auth

Fail closed.

expired token but scan continued

Halt and mark partial.

Why it happens

Error handling that logs and continues turns auth failures into silent data gaps.

Edge cases

• Distinguish expiry (refresh and resume) from revocation (stop and investigate).
• Partial results must never be presented as complete.
• Auth checks cost little; run them often.

Not specified by the original author.

TL;DR

Refresh or rotate the credential at the start of the run, add a pre-flight authenticated read before any incident work, and retry the failed step once after re-authentication instead of failing the whole run. Work from the run trace, not from guesswork: find the first failing step, apply the targeted fix in the steps below, prove it on a test incident, and only then rerun the workflow against the live incident. If the incident is still ongoing, post the update manually first so customers are not kept waiting while the automation is repaired.

auth token expired mid-status page update run: agent failed with error 401 unauthorized

Use this when

• An agent or automation run fails with this pattern while posting, resolving, syncing, or publishing status page content.
• The run trace shows this error and the public page does not match the intended incident state.
• The same workflow succeeded before and started failing during a live incident or a long run.
• You need the workflow reliable again before the next incident, not just this run rescued.

Not for this skill when

• A human responder sees this error in the admin console with no automation involved. Use the error-specific status page skill instead.
• The underlying product outage is still unresolved. This skill repairs the communication workflow, not the outage.
• You are evaluating agent frameworks in general. This skill only fixes the named failure pattern.

Steps

1. Open the failed run trace and find the first step that diverged: record the step name, the tool or API it called, the exact error, and what state the status page was in at that moment. Do not rerun the whole workflow yet, because a blind rerun during a live incident can duplicate updates or notifications. Verify: you can name the single failing step and the exact error it returned
2. Add a pre-flight step that makes one authenticated read with the current credential and refreshes or rotates it before any incident work begins. Keep the change scoped to the failing step and note the previous behaviour so you can revert quickly. Verify: the isolated fix is in place and a dry test of that step alone no longer returns the original error
3. Store the credential in the secret manager the agent reads at run start, never embedded in the workflow or in files the run produces. Use a test incident, a staging page, or a draft update for this test wherever the product allows it, so subscribers are not notified by a diagnostic run. Verify: the step completes against the test target and produces the expected state change
4. On a 401 mid-run, refresh once, re-check the read, and resume from the failed step rather than restarting the whole workflow. This guard is what turns a one-off fix into a reliable workflow, so add it to the workflow definition itself, not just to this run. Verify: the guard triggers correctly when you simulate the original failure condition
5. Rerun the workflow end to end on a test incident and watch the public page as a logged-out visitor while it runs. Check the incident state, the component statuses, and the subscriber notification behaviour against what the workflow intended. Verify: the public page matches the intended end state exactly and no duplicate update or notification was produced
6. Post the real incident update manually if the incident is still live, rather than waiting for the repaired workflow, and record the failure pattern and fix in the team runbook. Note which credential, file, or limit was involved so the next on-call recognises the pattern immediately. Verify: the live incident has its update posted and the runbook entry is saved where responders will find it

Why it happens

Long incident runs outlive short-lived credentials. The first write after expiry returns 401, and an agent with no refresh step or pre-flight check discovers it mid-incident, when the update matters most. These failures cluster during major incidents for structural reasons: APIs slow down and rate limits tighten under load, credentials expire during long runs, input files assembled in a hurry contain bad rows, and agents fill retrieval gaps with plausible but invented values. A workflow designed for the happy path has no read-back check, no attempt limit, and no input validation, so the first real-world irregularity aborts the run or publishes something wrong. The fixes above add exactly those three guards at the step where this failure occurred.

Variants and edge cases

Same failure pattern against a different status or incident API

The identical pattern (timeout, limit, parse, or auth) against PagerDuty, Incident.io, FireHydrant, Better Stack, or Opsgenie instead of Statuspage. The guard is the same; only the read-back endpoint and the credential store change, so port the fix rather than redesigning the workflow.

Failure only during major incidents, never in tests

Load-dependent variants pass every test and fail live. Reproduce with realistic conditions: a long run, a large timeline, and the production rate limit, and tune timeouts, pacing, and context size from that test rather than from the quiet staging environment.

Agent reports success but the page never changed

The most dangerous variant, where no error surfaces at all. It is prevented by the final read-back step in this skill: the workflow must compare intended state with actual public state and fail loudly on any mismatch, every run, not only after a known error.

Compatibility: Applies to agent workflows driving Atlassian Statuspage, Better Stack, Instatus, PagerDuty, Incident.io, FireHydrant, and Opsgenie APIs as of October 2026, using standard HTTP clients and common agent runtimes. Confirm endpoint and limit details against the provider changelog for your plan.
